Your question: What is the phenotype of the two alleles blend?

Incomplete dominance occurs when two heterozygous alleles are expressed together in the phenotype of an organism. The distinct phenotypes produced by each allele are blended together into a third phenotype.

Is when the phenotypes of two alleles blend together?

Codominance. Codominance refers to the dominance in which the two alleles or traits of the genotypes (of both homozygotes) are expressed together in offspring (phenotype).

What is a blended phenotype?

Explanation: A phenotypic “blending” of two traits is referred to as incomplete dominance, indicating that neither trait is truly dominant over the other. Instead of one color overpowering expression of the other, both colors are expressed simultaneously.

What is the phenotype of alleles?

Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. … Some alleles are dominant or recessive. When an organism is heterozygous at a specific locus and carries one dominant and one recessive allele, the organism will express the dominant phenotype.

How many phenotypes are possible with 2 alleles?

With two loci and two alleles in a strictly additive model (i.e., no epistasis or other modifying effects) we can have five phenotypic classes aabbWhen the phenotypes controlled by two alleles are equally displayed in the heterozygote the two alleles are said to show?

THIS IS IMPORTANT:  Question: Is it possible to be born with 45 chromosomes?

Codominance pertains to the genetic phenomenon in which gene products from the two alleles in a heterozygote are produced in roughly equal amount, where gene products refer to either different transcripts from the two alleles, different proteins from cellular processing of the transcripts, or different metabolites …

What is example of phenotype?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. … Examples of phenotypes include height, wing length, and hair color.

What does it mean to blend in?

Definition of blend in

1 : to look like things nearby The fish settles on the sandy ocean bottom where it blends in perfectly. 2 : to look like one belongs with a particular group She tried to blend in by dressing like the other girls.

What type of inheritance do two alleles have if their traits blend together?

One exception is incomplete dominance (sometimes called blending inheritance) when alleles blend their traits in the phenotype. An example of this would be seen if, when crossing Antirrhinums — flowers with incompletely dominant “red” and “white” alleles for petal color — the resulting offspring had pink petals.

Which is a phenotype?

A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

What’s genotype and phenotype examples?

For example, two mice that look virtually identical could have different genotypes. But if they have visibly different traits – say, one has white fur and the other has black fur – then they have different phenotypes.

What’s my phenotype and genotype?

An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. A change in the environment also can affect the phenotype. …

When both alleles are expressed equally in the phenotype of the heterozygotes?

Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote. The red and white flower in the figure has codominant alleles for red petals and white petals. Codominance.

How many phenotypes can be expressed?

There are three common alleles in the ABO system. These alleles segregate and assort into six genotypes, as shown in Table 1. As Table 1 indicates, only four phenotypes result from the six possible ABO genotypes.

Can two organisms have different phenotypes but the same genotype?

Can organisms with different genotypes have the same phenotypes? … The answer is yes, two different genotypes can result in the same phenotype. Remember, the recessive phenotype will be expressed only when the dominant allele is absent, or when an individual is homozygous recessive (tt) (Figure below).
